Rated 2970, Krush plays at a level spanning international master to grandmaster strength, combining accurate calculation in long forcing lines with a deep grasp of structure and plans. At 42, Krush's profile draws on a curated style rather than any single real-world game record. As White, Krush frequently steers play into the [Indian Game mainlines](/resources/openings/indian-game-mainlines), favoring flexible central control over e4 before committing to a plan. Opponents should expect a well-rounded test: sound opening choices, patient maneuvering, and sharp tactical awareness the moment the position opens up. Few amateur mistakes go unpunished against this bot.","42","legend_irina_krush","United States","us","4498bf7a8450130b58e9eae9c258b87c29c0127ad6128760731f711b6d687d01","2026-10-05",2970,"json",[15,18,21],{"question":16,"answer":17},"What rating is Krush?","Krush carries an estimated rating of 2970 on Chessiverse, placing the bot in international master to grandmaster territory.
